From therehe went 100 metres to his north beforemeeting his father in a street. Now howfar he is from his starting point?.4.
Answer» From the diagram, AB = 90-30 = 60 and BD = 100-20 = 80 AD = √AB²-BD² = √(60²-80²) = √10000 = 100 m Hit like if you find it useful!

From the diagram,

AB = 90-30 = 60 and BD = 100-20 = 80

AD = √AB²-BD² = √(60²-80²)

= √10000

= 100 m
